Given the syntax of this function, wgBreakFrames can only have one of two
values: true or false.

I'd be interested to see some POC that would show how you would exploit
this.

The first thing to do is abuse the variable. In addition to true and false, try
3, 0 , -37, "Cabbage", and maybe "true) and (my_evil_function()))". See if you
can force it to throw a syntax error that creates a 404 page or something that
contains *other* input you control, especially if it finds its way to an eval().
